wallet-v0.5.0
3b88df6

0.5.0 — 2026-04-11

Native UTXO management, coin selection, and automatic change handling.
The wallet can now fund transactions end-to-end without an external
wallet server — create_action with outputs but no inputs triggers
automatic UTXO selection, fee estimation, and change generation.

Added

  • UTXO management pipeline (#264): CoinSelector (exact-match,
    smallest-sufficient, largest-first), ChangeGenerator (BRC-29 multi-output
    change with dust consolidation), FeeEstimator (size-based sats/kB)
  • WhatsOnChainProvider — chain UTXO discovery via WhatsOnChain API
  • StorageAdapter extensions — 6 new interface methods
  • Atomic UTXO locking — closes TOCTOU race in concurrent selection
  • Auto-funding in create_action — automatic UTXO selection, fee
    estimation, and change generation

Fixed

  • Rate-limit release_stale_pending! to avoid O(n) scan per call
  • Validate tx_pos bounds in sync_utxos against untrusted API data
  • Align identity UTXO filter and signing path with storage schema
  • Match TS SDK no_send semantics for pending change and abort cleanup
